Answer is 20,16,12,8,4,0.
When i=-4 then
Because of if(-4>=-10)
It will not go inside if block
Because of -4 is bigger than -10 so,
Final answer is 20,16,12,8,4,0.

Here it is first printed and it is checked thats why we have -12 also and it comes out from loop.

First when it Enter into "forloop"
it prints "i" = "20"
it compares (i>-10) i.e (20>-10) is true
then it changes (i-=4) i.e 20-4=16 again stored in "i"
it prints "i" = "16"
it compares (i>-10) i.e (16>-10) is true
then it changes (i-=4) i.e 16-4=12 again stored in "i"
it prints "i" = "12"
it compares (i>-10) i.e (12>-10) is true
then it changes (i-=4) i.e 12-4=8 again stored in "i"
it prints "i" = "8"
it compares (i>-10) i.e (8>-10) is true
then it changes (i-=4) i.e 8-4=4 again stored in "i"
it prints "i" = "4"
it compares (i>-10) i.e (4>-10) is true
then it changes (i-=4) i.e 4-4=0 again stored in "i"
it prints "i" = "0"
it compares (i>-10) i.e (0>-10) is true
then it changes (i-=4) i.e 0-4=-4 again stored in "i"
it prints "i" = "-4"
it compares (i>-10) i.e (-4>-10) is true
then it changes (i-=4) i.e -4-4=-8 again stored in "i"
it prints "i" = "-8"
it compares (i>-10) i.e (-8>-10) is true
then it changes (i-=4) i.e -8-4=-12 again stored in "i"
it prints "i" = "-12"
it compares (i>-10) i.e (-12>-10) is False
The break statement is Executed then it jumps out of the loop.

@Latha, It is not 10, but -10 (minus 10). So the answer for sure is C.

While Compilation it shows only from 20 to -12.

To the people starting programming, please use curly braces ({}) in your conditional statements. They say you can't teach an old dog new tricks. You have been warned.

Can we write break statement in else?

Output will be 20, 16, 12, 8:
When var i is 8 then if(i>=10) condition is fail and go to break.
So, How will be the answer is [C].

All three conditions of for loop is optional.
-12 because after checking for -8 it will decrements it to -12 then print it then check for -12 which break the loop.
